IMPROVEMENT IN BOOTS AND SHOES.

Specication forming part of Letters Patent No. 213,217, dated March 11,1879; application liled February 5, 1879.

To all whom it may concern:

Be it known that I, LAZARUS LOESER, of the city, county, and State ofNew York, have invented a new and useful Improvement in Boots and Shoes,which invention is fully set forth in the following specification,reference being had to the accompanying drawings, in which- Figure lrepresents a longitudinal vertical section. Fig.2 is an inverted plan oftheinsole.

Fig. 3 is a transverse section in the plane .r w,-

nair-channel in the heel, and when the pressure on the insole relaxesfresh air is sucked in through said air-channel. The air between theinsole and the outsole communicates with the interior ofthe boot or shoethrough perforations in the insole.

On the under surface of the insole are formed suitable ridges, toprevent the same from closing down tight upon the inner surface of theoutsole.

A suitable register serves to open or close the air-channel in the heel.

In the drawings, the letter A designates the heel of a boot or shoe. Bis the insole, and O the outsole. In the heel is formed an airchannel,a, (one or more,) which communicates with an air-space, b, formedbetween the insole B and the outsole C.

In the example shown in the drawings the air-channel a opens at thebreast of the heel, so that it is not visible when the boot or shoe isworn.

The airspace bis formed by means of ridges c, which project from theunder surface of the insole; or, if desired, such ridges may be formedon the inner surface of the sole C without deviating from my invention.

Between the insole B and the outsole C is situated a spring, D, which ispreferably fastened to the insole, as shown in the drawings, and whichis situated beneath the ball of the foot. If desired, two or more suchsprings may be applied.

By the action of this spring the insole is forced away from the outsole;but whenever the ball of the foot is brought to bear down upon theinsole the spring D is compressed, and the air from the air-space bisexpelled through the channel a, and when the pressure upon the springrelaxes a quantity of fresh air is drawn in the airfspace.

The insole B is perforated with a number of holes, d, through which theair-space b communicates with the interior of the boot or shoe 5 andsince at every step the spring D is first compressed and then relaxed,the damp air from vthe interior of the boot or shoe is first expelled,and then replaced by fresh air from the outside, and by these means acomplete ventilation of the boot or shoe is effected.

On the mouth of the air-channel a is placed a register, e, which can beopened or closed,

so that in wet weather the moisture from thev outside is prevented frompassing into the boot or shoe.

My invention is applicable to boots and shoes made of india-rubber orany other material, as well as to boots and shoes made of leather.

What I claim as new, and desire to secure by Letters Patent, is-

1. The combination, in a boot or shoe, of an air-channel, (one or more,)extending through the heel, an air-space formed between the in sole andthe outsole, and communicating with said air-channel, and a spring, (oneor more,) placed between the insole and the outsole, all constructed andadapted to operate substan-V tially as and for the purpose shown and described. l

2. The air-channel a., located in the heel of a boot or shoe, made tocommunicate with the external air through the breast ofthe heel, incombination with the air chamber or space b, intervening between theperforated insole and the inner surface of the outer sole,substantiall)7 as an d for the purpose speciiied.
